My daughter is currently semi toilet training herself.  When left without a nappy on she will take herself to the potty for number 2s, but, alas, not number 1s.  Occasionally she has done a wee, but not very often and largely when prompted.  So, imagine my pleasure when my son comes running to me:

"Mummy you have to come and empty Bella's wee out of the potty"

"Oh, OK" I respond and come running

Bella is just getting off the potty and I was very surprised to see about an inch of liquid in the potty - "Wow!" I exclaim!  Then realisation dawns - "it's very clear for wee!" I say.... mmmmm...

R responds, "we tricked you mummy, it was a joke, it's just water!"

Funny.....
